980nm, 12.5mm Diameter, OD 4.0 Notch Filter

Product Details >OD 4.0 Rejection of Laser Wavelength from 355nm to 1064nm Broad Transmission Range OD 6.0 Notch Filters Also Available Low Cost Alternative to Rugate Notch Filters TECHSPEC OD 4.0 Notch Filters are low-cost alternatives to Rugate Notch Filters. The filters feature narrow rejection bands of just ±2.5% of the center wavelength while offering greater than 99% reflection of the laser wavelength. These optical filters have a broad transmission range and are hard coated to guarantee performance that will not degrade with time, temperature, or humidity. TECHSPEC OD 4.0 Notch Filters are mounted in a black anodized ring engraved to ease filter handling, identification, and orientation. OD 6.0 Notch Filters are also available for purchase. Note: These filters are optimized for high spectral performance rather than high Laser Induced Damage Thresholds (LIDT). A typical LIDT for these filters is 1 J/cm 2 @ 532nm, 10ns. Please contact us if you require a filter with a higher LIDT value.
